Well, it happened on both of the new machines we got last week. One
of these is still up BTW and I'm able to ssh into it.

There's no such message in the log. The preceeding lines are just normal
startup messages:

	Adding 16779852k swap on /dev/sda1.  Priority:42 extents:1 across:16779852k
	Adding 16779852k swap on /dev/sdb1.  Priority:42 extents:1 across:16779852k
	process `syslogd' is using obsolete setsockopt SO_BSDCOMPAT

Thanks for the quick response.
